Using the Illawarra and South Coast NSW rainfall forecast safely

This map is forecast guidance, not a warning. Totals change with every model run, and a single storm can drop far more rain on one catchment than the map suggests. Official rainfall, flood and severe weather warnings from the Bureau of Meteorology always take priority for the Illawarra and South Coast. Never drive through floodwater.

For rain already falling, use the rainfall radar and observations. For storm risk, see the Illawarra and South Coast NSW thunderstorm forecast map.
